, S m-M INE Specification of Letters Patent No. 7,396, dated May 28 1850.

T 0 all whom z'tmay concern Be it known that we, OYIiUs D GOR ON,

of West Martinsburg, and SAMUEL S.

GOULDTHRITE, 'ofLowville, inthe county of Lewis and StateofNew York, have invented a new and useful Improvement n Smut-Machines for separating-and fremov ing the smut, dirt, or other foreign from wheat or other grain 5 and" we do here= by declarethat tl ie-following-is a-full, clear,

and"exact-description of" the Sa refililcl beinghad to the accompanying drawings, in wh1ch-- Figure 1 1sa general vlew of themachine.

Fig. 2 is a vertical section through the center. Fig. 3 is an inverted planor view of the bottom ofthe machine. Fig. 4 is a plan ofthe revolvingwinged drum; Fig. 5 1s a horizontal sectionahrough the line 00 w of Fig. 2. Fig. 6*representson a larger scale a part of the ou tercasing in section.

Similar letters ref'er"to corresponding It isprovicledwithwings f,f, f, audslots parts, in the several figures? The nature of our lnventlon consists in scouring wheat or other grain between two plates havingwavedand fluted surfaces.

One of these plates isstationary andforms the upper plate of'the outer casing of the carried off through apertures in the outer casing by a current of air which is caused to circulate through the machine by means of the revolving drum. The vertical shaft on which the revolving drum is mounted is provided with a cup into which the grain is fed passing through apertures in its lowerpart on to the plate of the revolving cylinder by feeding from the center We are enabled to use the entire working surface of the plates, and to take the grain from any direction in the roomwithout moving the machine.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation. a

A is the outer casing or curb, the upper diameter of which is greater than the lower.

It isformed of stout sheetf iron and corrw gated orfiuted. Itis provided with slots or apertures a, a, a, and is firmly held by bolts 13,13," B, between the stationary circular plates C, and D, which are grooved to re ceive it. "The "upper stationaryplate 0,11% a series of waves Z), b 'b, concentric toit and is provided with slots 0, 0,10, radiating from r the center and intersectingtl'iewaves I 5,19." These slots 0, 0, c, are to allowthe eiiit of the dirt,butarenotlarge enough to allow the grain to pass out.

The plate C, is" "further provided with larger concentric slots or apertures d, 9?,

nearits outer circumference. k y y L The lower stat onary plate D is provided with a large circularaperture at its center E, is the revolving drum which is of strong sheet iron ofthe form of' the inverted frusi ith other concentric slots or apertures tum of a conebeing smaller atits lower end. i

or apertures g, g, g

of the revolving dmmwhidi provided on its upper surface with aseries of concentric] waves 22, b, b, correspondingwith those 1 b, 79,1),011 theunderside of the stationary plate C. These wavesare providedfwith grooves or fiutesh, h,h,ra'd1al tothe center. a, a, 2,2are circularconce'ntr c grooves in the plate F theunder side ofthe stationary 1 plate C, is alsop1'oyicled with grooves or flutes correspondingwith those l1, h, h, and

Z, Z, Z, on the plate F. r

G, is the lower circular plate or bottom of the revolving'clrum. It is provided with apertures j, j.

H, is the vertical shaft which carries the revolving drum being fitted and keyed or suitably secured in the plates F and G.

I, is a yoke which is bolted to the under side of the plate G, and carries a boss J, in which is inserted a screw K, having a recess in its upper end forming a step-bearing for the lower end of the vertical shaft H. The screw K may be screwed up or unscrewed to raise or lower the revolving drum and regulate the space between the plates C and F. The boss J, has arecess on its upper .side forming an oil cup.

L, is a set or jam nut for the purpose of tightening and securing the screw K in any a box M.

are the means of adjusting the said shaft in a vertical position.

0, is the driving pulley on the shaft H, and is driven by an endless band P. The outer casing together wit-h its upper and lower stationary plates, may be supported in any convenient manner on the floors of the mill or building in which the machine is worked.

The operation is as follows: Motion being communicated to the revolving winged drum by means of the band P, and pulley O, the grain is fed into the cup Q and as it (the cup) revolves the grain will pass out by the apertures 70, 7c, and between the stationary plate G, and the upper plate F of the revolving drum and will pass between the concentric grooves z, 2', 2', and over and between the waves 6, b, b, and b, b, b, and between the grooves or flutes h, h, 71. vVhereby the smut balls will be broken and the dirt, &c. separated from the grain, and should any oats become accidentally mixed with thewheat the hulls will be broken and separated. By the revolutions of the circular winged drum E, the circle described by the lower ends of the wings being smaller than that described by the upper ends and the annular space between the drum and the outer case'being smaller at the lower part, a current of air will'be caused to circulate through the large circular aperture in the plate D, and also through the slots 6, e, in the said plate and will pass upward in The blocks N, N, N, N, form the guides of the upper end of the shaft H, and

the direction of the arrows shown in Fig.2, of the drawings between the drum and the outer casing. It will also pass through the apertures 7', -j, in the lower revolving plate and through the slots 9, g, g, in the drum E, into the said space between the drum and the .outer casing. The greater .part of the dirt 'lwill be carried by the said current of air out by the slots 0, 0, 0, intersecting the waves 6, b, b, in the stationary plate C, while the White caps andother light matter'too large to pass out at 0, c, 0, will go out at the larger apertures cl, 0?.

After the grain has been passed between the plates C, and F by the revolution of the i drum it will fall over the edges of the plate F to the bottom stationary plate G, of the outer casing and will pass out by the apertures or slots 6, e, the current, of air through the slots g, g, g in the drum having carried out the remaining dirt through the apertures or slots at, a, a, in the outer casing A the said apertures not being large enough to allow the grain to pass out.

What we claim as new in our invention and desire tosecure by Letters Patent, is

l. The combination of the cup Q, with the shaft H for the purpose of receiving the grain and conducting it all around between the plates C, and E, as herein described.

2. The adjustable bearing or guide for setting the the shaft H vertical, consisting of the box M, the blocks N N N N and the -screws 1% n n n, constructed and arranged as herein set forth.

8. The circular revolving winged and slotted drum E in combination with the scouring plates C and E in the manner substantially as described, producing a'current of air for carrying o the smut, dirt, and other foreign matter.
